I remember that when Thomas Hauk used gnubg in his thesis on search trees with
chance nodes, he converted the floating point operations to integers. The
stated purpose was to avoid any inconsistencies due to rounding errors, but he
also claimed that the integer maths had a slightly better performance.
Is there any benefit in looking into this? I believe that his version of gnubg
was pre-SSE, so that work may have surpassed any benefit from integer maths.
